Fabrication and Characterization of Novel AgNPs Functionalized with Chlorothymol (C@AgNPs) [PDF]

, 2022
In this study, novel silver nanoparticles (AgNPs) were successfully synthesized and functionalized with an antibacterial agent, namely chlorothymol (denoted C@AgNPs). The resulting colloid (C@AgNPs) was purified by two comparative methods: ultrafiltration and ultracentrifugation.

The Influence of Reagents on the Shape, Stability, and Toxicity of AgNPs and Their Use to Produce Polymer-AgNPs Composites

Metals, 2023
The aim of this work was to propose a simple method for synthesizing differently shaped AgNPs and to find a suitable stabilizing/capping agent to ensure the non-toxicity of AgNPs. Using a chemical method, by simply changing the volume of reducing agents, we successfully prepared colloids of differently shaped AgNPs (spherical (~10 nm), triangular (~40 ...

Comparative Analysis Of Antibacterial And Antifungal Activity Of AgNPs With Conjugated Curcumin AgNPs

TSF Journal of Biology, 2023
Silver nanoparticles (AgNPs) are potent antimicrobial agents, extensively used against a wide variety of microorganisms. Several techniques have been developed to chemically synthesize silver nanoparticles but limited their application due to their cytotoxicity and safety concerns for humans and the environment.

Small AgNP in the Biopolymer Nanocomposite System [PDF]

International Journal of Molecular Sciences, 2020
In this work, ultra-small and stable silver nanoparticles (AgNP) on chitosan biopolymer (BP/AgP) were prepared by in situ reduction of the diamminesilver(I) complex ([Ag(NH3)2]+) to create a biostatic membrane system. The small AgNP (3 nm) as a stable source of silver ions, their crystal form, and homogeneous distribution in the whole solid membrane ...

Surface modification of silver nanoparticle (AgNP) by liposomal encapsulation mitigates AgNP-induced inflammation [PDF]

Toxicology in Vitro, 2019
Silver nanoparticles (AgNP) are widely used in a variety of consumable products as antibacterial to prevent or treat infection. Unfortunately, evidence exits that AgNP induces inflammation which can worsen with repeated human exposure. However, there is little or no research on how to mitigate these adverse effects due to AgNP induced-toxicity.

PSEUDOPEROXIDASE ACTIVITY OF SILVER NANOPARTICLES (AgNPs) AND CHANGES IN PEROXIDASE ACTIVITY IN MAIZE PLANTS EXPOSED TO AgNPs [PDF]

NANOCON Conference Proeedings, 2020
Some types of nanoparticles such as gold and silver show interesting chemical properties. Pseudoperoxidase activity has been found in iron- or gold-based materials, but some silver nanoparticles (AgNPs) also exhibit such properties. Pseudoperoxidase activity of AgNPs prepared by green synthesis using sage leaves was studied.

Surface Engineering of AgNPs-Decorated Polyetheretherketone

International Journal of Molecular Sciences, 2023
Metal nanostructure-treated polymers are widely recognized as the key material responsible for a specific antibacterial response in medical-based applications. However, the finding of an optimal bactericidal effect in combination with an acceptable level of cytotoxicity, which is typical for metal nanostructures, prevents their expansion from being ...
